The report worked out what NAEP scale score was equivalent to each state's proficiency cut score. Using that method, the 2007 portion of the study shows that:
- Only 35 percent of states with reported data had higher fourth grade reading proficiency standards than Kentucky.
- Only 29 percent had higher eighth grade reading standards.
- Only 29 percent had higher fourth grade mathematics standards.
- Only 23 percent had higher eighth grade mathematics standards.
The proficiency standards set in 2007--and used in this NAEP comparison--are scheduled to stay in use through 2011. In 2012, Kentucky will launch new tests required by Senate Bill 1, including new definitions of what scores qualify as proficient.
